Write sentences for the ear: one idea at a time, explicit transitions, and punctuation that creates natural pauses. Spell out abbreviations or numbers that the voice may pronounce incorrectly.
Avoid references such as “see the table above” when listeners will not see the page. Preview the audio, listen without reading along, and revise awkward sections. Keep the original script so you can compare changes later.
